Fuel accounts for 30-40% of total operating costs for transport companies, and it's also the expense most prone to loss without a strict management system. Effective fuel cost control not only helps businesses increase profits but also enhances competitive capacity in the market. This article will provide detailed guidance on building a comprehensive transport fuel management process, from establishing consumption norms to applying modern monitoring technology.

Why Fuel Management Is Critical for Transport Businesses

Truck fuel costs are one of the largest expenses that any transport business faces daily. According to statistics, each truck consumes an average of 3,000-5,000 liters of fuel per month, equivalent to 60-100 million VND in fuel costs.

Alarming reality:

  • 15-30% of fuel is lost due to fraud, loose management, or inefficient driving
  • Lack of systems to track standard fuel consumption norms for each vehicle type
  • Failure to detect fraud behaviors such as fuel siphoning or falsifying fuel quantities
  • Waste due to non-optimized routes, empty runs, or poor maintenance

Benefits of strict fuel management:

When implementing effective TMS fuel management, businesses can:

  • Reduce fuel costs by 15-25% through detecting and preventing fraud
  • Increase profits by 8-12% from fuel savings alone
  • Improve labor discipline and savings culture in the fleet
  • Have accurate databases for negotiating transport rates
  • Accurately forecast fuel budgets for each quarter/year

A business with 20 trucks, if saving 20% on fuel costs, will save about 240-480 million VND/month. This figure is enough to see the importance of transport fuel management.

Building Standard Fuel Consumption Norms for Each Vehicle Type

Fuel consumption norms are the foundation of all monitoring and control activities. Without standard norms, you cannot detect abnormalities.

Factors Affecting Consumption Levels

Fuel consumption norms are not fixed numbers but depend on many factors:

1. Vehicle characteristics:

  • Vehicle type (light, medium, heavy truck), engine capacity
  • Vehicle age (older vehicles typically consume 10-15% more fuel)
  • Technical condition and maintenance

2. Operating conditions:

  • Type of goods and payload (fully loaded vehicles consume 30-40% more fuel than unloaded)
  • Terrain (mountains, plains, highways)
  • Traffic conditions (urban, suburban)
  • Weather and seasons

3. Human factors:

  • Driving skills and habits
  • Fuel-saving awareness

Methods for Building Standard Norms

Step 1: Collect actual data

Over 2-3 months, record completely:

  • Kilometers traveled by each vehicle
  • Liters of fuel filled (with invoices)
  • Cargo payload per trip
  • Journey type (long, short distance, terrain)

Step 2: Calculate average consumption

Basic formula:

Consumption rate (liters/100km) = (Total liters consumed / Total km) × 100

However, need to separate by different conditions:

  • Consumption when running unloaded
  • Consumption when fully loaded (50%, 75%, 100% payload)
  • Consumption by terrain type

Step 3: Reference manufacturer specifications

Compare with vehicle manufacturer norms and adjust to suit Vietnamese conditions (typically 10-20% higher due to road and traffic conditions).

Step 4: Establish standard norms

Example norms for 8-ton truck:

  • Unloaded: 16-18 liters/100km
  • Fully loaded highway: 22-25 liters/100km
  • Fully loaded city roads: 28-32 liters/100km
  • Fully loaded mountain roads: 30-35 liters/100km

Step 5: Set warning thresholds

Allow ±5-7% margin of error from the norm. Exceeding this threshold requires immediate inspection.

Regular Norm Updates

Fuel consumption norms need to be reviewed and adjusted:

  • Every 6 months or when the vehicle has traveled 50,000 km
  • When changing fuel type or supplier
  • After major repairs or maintenance
  • When fuel prices fluctuate significantly

Effective Fuel Tracking Methods: From Manual to Automatic

Manual Method - Suitable for Small Businesses

1. Paper fuel tracking logbook

Drivers record:

  • Date and time of refueling
  • Liters and amount
  • Odometer reading
  • Refueling location
  • Confirmation signature

Advantages: Low cost, easy to implement Disadvantages: Easy to commit fraud, lack of accuracy, difficult to consolidate data

2. Centralized Excel spreadsheet

Office staff enters data from paper logbooks into Excel, calculating:

  • Actual consumption rate/vehicle/day
  • Comparison with norms
  • Total fuel costs

Advantages: Easy calculation, basic reporting Disadvantages: Still relies on manual data, slow updates

Semi-Automatic Method

1. Fuel Cards

Using cards from oil companies (Petrolimex, Saigon Petro...):

  • Drivers use cards to refuel
  • System automatically records liters, price, time
  • Business receives periodic reports

Advantages:

  • Reduces fraud regarding amounts
  • Easy reconciliation
  • Discounts from oil companies (2-5%)

Disadvantages:

  • Still don't know actual kilometers traveled
  • Cannot detect fuel siphoning after refueling

2. GPS system + electronic diary

Combining GPS tracking with electronic records:

  • GPS tracks actual kilometers
  • Drivers photograph fuel receipts, send via app
  • Software calculates consumption rate

Advantages: Increased accuracy, harder to commit fraud Disadvantages: Still requires manual fuel data entry

Automatic Method - Optimal Solution

1. Fuel level sensor + GPS + TMS

Integrated system:

  • Sensor accurately measures fuel level in tank (error <1%)
  • GPS tracks location and distance
  • TMS software automatically calculates and alerts fleet fuel management

Operating process:

  1. Sensor measures fuel level in real-time (every 30-60 seconds)
  2. GPS records accurate kilometers traveled
  3. Data transmitted to TMS server via GPRS/3G/4G
  4. System automatically:
    • Compares with fuel consumption norms
    • Detects abnormalities (refueling, siphoning, high consumption)
    • Sends instant alerts via app/SMS/email
  5. Creates automatic daily/weekly/monthly reports

Advantages:

  • Highest accuracy
  • Detects fraud immediately
  • Saves management time
  • Comprehensive data for analysis

Disadvantages:

  • Initial investment cost (3-5 million/vehicle)
  • Requires staff training

2. Integration with overall management system

Fuel monitoring solutions integrated in TMS software like DeliTMS:

  • Connects with sensors, GPS, dashcams
  • Centrally manages routes, orders, fuel, drivers
  • Optimizes routes to save fuel
  • Multi-dimensional reporting, trend analysis

Identifying 7 Most Common Fuel Fraud Signs

Detecting fuel fraud is one of the most important tasks in transport fuel management. Below are 7 common tactics and how to identify them:

1. Siphoning After Refueling

Tactic: Driver fills tank, takes receipt, then siphons 10-20 liters to sell or use for personal vehicle.

Identification signs:

  • Consumption 15-25% higher than norm
  • Fuel level graph drops suddenly after refueling (if sensor installed)
  • Vehicle refuels but kilometers between refuelings are abnormally low

Detection method: Use fuel level sensor combined with GPS. When sudden fuel level decrease (>5 liters) occurs while vehicle is parked or moving short distance, system alerts.

2. Falsifying Fuel Quantity

Tactic:

  • Refuel 50 liters but claim 70 liters
  • Collude with gas station staff to create fake invoices
  • Alter receipts (erase, photoshop)

Identification signs:

  • Liters on receipt exceed tank capacity (e.g., 200-liter tank, 50 liters remaining but refueling 180 liters)
  • Refueling frequency too high (e.g., refueling twice/day for city vehicle)
  • Amount on receipt doesn't match listed price

Detection method:

  • Check logic: (Tank capacity - Remaining fuel level) >= Liters refueled
  • Cross-check receipt price with official price list
  • Use fuel cards with limits based on norms

3. Refueling at "Ghost" Stations

Tactic: Refuel at acquaintance's station at actual price 20,000 VND/liter but invoice shows 23,000 VND/liter, splitting the difference.

Identification signs:

  • Always refuel at same station despite other closer stations
  • Station location deviates from main route
  • Receipt price higher than market price

Detection method:

  • GPS tracks refueling location, compares with route
  • Specify list of authorized gas stations
  • Check receipt price against publicly listed prices

4. Running Private Trips, Using Company Fuel

Tactic: Using company vehicle for personal trips (hauling goods for extra income, picking up relatives), consuming company fuel.

Identification signs:

  • Actual kilometers much higher than kilometers per dispatch order
  • Vehicle moves outside work hours, holidays
  • Route deviates from standard path
  • Travel time abnormally extended

Detection method:

  • GPS tracks real-time route, compares with dispatch order
  • Dashcam records cargo type and passengers
  • Cross-check GPS kilometers with odometer

5. False Payload Reporting

Tactic: Vehicle runs fully loaded but reports running unloaded or 50% loaded to justify high consumption (after siphoning fuel).

Identification signs:

  • Consumption higher than unloaded norm
  • Doesn't match order data in system
  • Payload information contradicts documents

Detection method:

  • Cross-check with dispatch orders and orders in TMS
  • Use load sensors
  • Check cargo transport documents

6. Collusion Between Drivers and Management Staff

Tactic: Dispatchers or fuel managers provide cover, ignore abnormalities for profit.

Identification signs:

  • Some vehicles always "overlooked" when abnormalities occur
  • Management staff over-explains cases exceeding norms
  • No measures taken when violations detected

Detection method:

  • Automatic alert system, not dependent on people
  • Clear authorization, cross-checking
  • Surprise inspections by higher levels

7. Fraud During Maintenance and Repairs

Tactic: Unauthorized modification of fuel system to increase consumption or facilitate siphoning.

Identification signs:

  • Consumption suddenly increases after repairs
  • Fuel sensor errors or unstable data
  • Evidence of tampering with fuel system

Detection method:

  • Regular technical inspections
  • Seal sensors and critical systems
  • Compare consumption before and after maintenance
